I've heard that the foreskin should roll back completely, but mine doesnt quite do that. The front part rolls back, but the back seems to stay attached to my penis. How can I get it to roll back completely and expose the red part?
The issue you're describing is related to a condition called phimosis, where the foreskin is partially or completely unable to retract over the glans penis; to address this, gently stretch the foreskin over time through manual retraction, using lubricants to reduce friction, and consider consulting a urologist or healthcare professional for guidance on proper technique and potential treatment options, such as topical creams or, in severe cases, circumcision.
